I hate these comparisions, they don't do anything. It's like saying Chuck Liddell is just like Rampage, and the only reason he has such a big following is because Rampage didn't come to the UFC till later in his career.
Chuck Liddell made a name for himself KOing B level fighters. That's not to say that he doesn't have wins over top fighters, but just that there is a lot of them who aren't top of the pack fighters.
Chuck Liddell = Chuck Lidell
